The invention relates to a telescopic mechanism of a pinion-and-rack container spreader. The telescopic mechanism comprises a main beam, a front middle beam, a rear middle beam, a front end beam and a rear end beam, wherein the front middle beam is arranged at the front end of the main beam, the rear end of the front middle beam is connected with the main beam by plugging and in telescopic fit with the front end of the main beam, the front end beam is arranged at the front end of the front middle beam and in telescopic fit with the front middle beam; the rear middle beam is arranged at the rear end of the main beam, and the front end of the rear middle beam is connected with the mean beam by plugging and in telescopic fit with the rear end of the main beam; the rear end beam is arranged at the rear end of the rear middle beam and in telescopic fit with the rear middle beam; and the maim beam is provided with a motor and a motor reducer, and a gear and rack drive mechanism is arranged between the motor reducer and the end beam. The gear and rack drive mechanism is reasonable in design, and convenient to maintain. The defects such as oil leak, high failure rate, complex and difficult maintenance and the like of hydraulic telescopic container spreaders are overcome.
